Iron Chlorosis Tree Fertilizer Spikes, Plant Food Spikes for Tree & Shrubs - Easy Application, Treats Common Deficiencies - Iron, Nitrogen, Sulfur, Phosphaate, Potassium - Pack of 40

Great value for money! The spikes are a great size for starter trees which is what I used them on. The directions are very clean on how to install. After a week the trees were starting to make a noticeable change in color, more green and are thriving. Will be using these again next year!

Sticks seem to be good in quality and went into the ground without crumbling . It's been a month since using and everything is still intacted.

great i built 3 ft 2 in pvc pipes and cut 6 holes in them; now I slide a sphere of fertilizer down them; 2 tubes per tree drive in about 2 feet

Helped with chlorosis, but did not clear up the problem.

These spikes are very durable and very well packaged. The box is heavy cardboard with a divider to keep the spikes from moving during shipment. Looking forward to how th is work next spring.

I use this on my Christmas trees in the backyard and they’ve grown enormously

We’re delivered quickly, very well packaged. Spikes held up well during installation. Will definitely purchase again.

Impressive. We will see if they work. Went into ground easily!
